Thanks youm0nt...The company"s Ultrastar 146Z10 hard drive incorporates anti-vibration technology that IBM calls "rotational vibration safeguard"--technology designed to improve the performance of increasingly denser and faster hard drives.
Drives are made up of components called platters and heads. Platters are the magnetic, rotating plates that store data, while heads pull the data off the rotating platters. To improve performance, manufacturers have increased the speeds at which platters rotate, and in turn, the rate at which heads pull information from those platters.
Yet in situations where servers are stacked atop one another, vibrations can disrupt other hard drives in the stack. The Ultrastar hard drive compensates for the shaking and works to cancel it out, IBM says. The new 146GB drive offers a speed of 10,000rpm.
